Seat assembly for a vehicle seat, method for assembling a seat assembly, and vehicle seat

Abstract

A seat assembly for a vehicle seat may have a structural component with multiple reinforcing ribs, a cushion layer, an insert layer which is arranged between the structural component and the cushion layer, at least one component which is secured to the structural component, and at least one securing device. The at least one securing device may secure both the insert part as well as the component to the structural component. A method for assembling such a seat assembly is also described. In one method step, the insert part is secured to the structural component by at least one securing device, and in the same method step or a subsequent method step or a preceding method step the at least one component is secured to the at least one securing device. A vehicle seat have such a seat assembly is also provided.

 b) an upholstery layer, 
 c) an insert part which is arranged between the structural component and the upholstery layer, 
 d) at least one component part which is fastened to the structural component, 
 e) at least one fastening means, wherein the at least one fastening means fastens the insert part to the structural component, and the at least one fastening means fastens the component part to the structural component, 
 
       wherein a material stiffness of the structural component is greater than a material stiffness of the insert part, wherein the material stiffness of the insert part is greater than a material stiffness of the upholstery layer. 
     
     
       2. The seat assembly as claimed in  claim 1 , wherein the seat assembly is embodied as a backrest. 
     
     
       3. The seat assembly as claimed in  claim 1 , wherein the structural component is manufactured from a fiber composite material. 
     
     
       4. The seat assembly as claimed in  claim 3 , wherein the fiber composite material comprises a thermoplastic matrix which is reinforced with glass fibers and/or carbon fibers. 
     
     
       5. The seat assembly as claimed in  claim 1 , wherein the structural component comprises a formed organosheet with stiffening ribs that are applied by injection molding. 
     
     
       6. The seat assembly as claimed in  claim 1 , wherein the structural component has at least one fastening dome to which the at least one fastening means is fastened. 
     
     
       7. The seat assembly as claimed in  claim 1 , wherein the insert part is manufactured from an expanded polypropylene. 
     
     
       8. The seat assembly as claimed in  claim 1 , wherein the insert part has a plurality of grooves for receiving stiffening ribs of the structural component. 
     
     
       9. The seat assembly as claimed in  claim 1 , wherein the at least one fastening means is embodied as a fastening clip. 
     
     
       10. The seat assembly as claimed in  claim 1 , wherein the at least one fastening means has a clip foot for fastening the fastening means to the structural component, including wherein the clip foot has a plurality of barbs. 
     
     
       11. The seat assembly as claimed in  claim 1 , wherein the at least one fastening means has a fastening part for fastening the component part to the at least one fastening means. 
     
     
       12. The seat assembly as claimed in  claim 1 , wherein the component part is a cable, including a cable harness. 
     
     
       13. A method for assembling a seat assembly, comprising:
 a) providing a structural component with a plurality of stiffening ribs, 
 b) providing an upholstery layer, 
 c) providing an insert part which is arranged between the structural component and the upholstery layer, 
 d) providing at least one component part which is fastened to the structural component, 
 e) providing at least one fastening means, wherein the at least one fastening means fastens the insert part to the structural component, and the at least one fastening means fastens the component part to the structural component, wherein the insert part is fastened to the structural component by means of the at least one fastening means, and in the same method step or a subsequent method step or a preceding method step, the at least one component part is fastened to the at least one fastening means, 
 
       wherein a material stiffness of the structural component is greater than a material stiffness of the insert part, wherein the material stiffness of the insert part is greater than a material stiffness of the upholstery layer. 
     
     
       14. A vehicle seat comprising a seat assembly assembled by means of a method as claimed in  claim 13 .
